Description

Technical Field

[0001] This utility model relates to the technical field of relays, and in particular to a novel relay housing. Background Technology

[0002] A relay is an automatic control switching element widely used in industrial automation, power systems, electronic equipment, home appliances, automotive electronics, and intelligent control systems. It controls the switching of large currents with a small current, achieving automatic switching and protection functions in circuits.

[0003] The relay housing plays a crucial role in the overall design of the relay. It not only protects the internal electronic components from external environmental factors (such as moisture, dust, mechanical shock, etc.), but also provides a certain degree of electrical isolation and heat dissipation.

[0004] The design of heat dissipation vents in relay housings is common, aiming to effectively dissipate internal heat and prevent performance degradation or damage due to overheating. However, this also brings another problem: when heat dissipation is not required, external dust may enter the housing through these vents, accumulating on the relay and its electronic components, potentially leading to electrical malfunctions or reducing equipment lifespan. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a new type of relay housing that, by setting this device, can seal the air inlet and outlet of the housing when heat dissipation is not required, thereby preventing dust from accumulating on the relay and its electronic components and ensuring its reliability.

[0006] This utility model discloses a novel relay housing, comprising a housing and two sets of sealing devices. An air inlet is connected to the lower left side of the housing, and an air outlet is connected to the upper right side. The two sets of sealing devices are respectively installed at the air inlet and air outlet of the housing. Each sealing device includes a sealing plate, two sets of fixed plates, a screw, a movable plate, and a motor. A movable groove is connected to the bottom of the air outlet of the housing, allowing the sealing plate to slide within the movable groove and seal the air outlet. Two sets of fixed plates are symmetrically installed on the right side of the housing, and the screw is rotatably installed inside the two sets of fixed plates. A long groove is connected to the outer end of the movable groove of the housing. The movable plate is installed on the lower right side of the sealing plate and slides within the long groove of the housing. The movable plate has a threaded hole and is threadedly connected to the screw. The motor is installed at the bottom of the lower fixed plate, and the motor output end passes through the lower fixed plate and connects to the bottom of the screw.

[0007] Preferably, it also includes a fan, which is installed at the air outlet of the housing.

[0008] Preferably, it also includes a dustproof net, which is installed at the air inlet of the outer casing.

[0009] Preferably, it also includes multiple sets of temperature sensors, all of which are equally installed inside the housing.

[0010] Preferably, it also includes a display screen, which is mounted on the left end of the housing and is electrically connected to multiple temperature sensors.

[0011] Preferably, a sealing ring is provided on the outer side of the sealing plate.

[0012] Preferably, the multiple temperature sensors are electrically connected to the fan and the two sets of motors.

[0013] Preferably, the outer shell is made of flame-retardant engineering plastic and meets the UL94V0 fire protection standard.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting this device, when heat dissipation of the casing is not required, the air inlet and outlet of the casing can be sealed, thereby preventing dust from accumulating on the relay and its electronic components, and ensuring its reliability in use.

[0019] like Figures 1 to 4 As shown, this utility model discloses a novel relay housing, comprising a housing 1 and two sets of sealing devices. An air inlet is connected to the lower left side of the housing 1, and an air outlet is connected to the upper right side of the housing 1. The two sets of sealing devices are respectively installed at the air inlet and air outlet of the housing 1. Each sealing device includes a sealing plate 2, two sets of fixing plates 3, a screw 4, a movable plate 5, and a motor 6. A movable groove is connected to the bottom end of the air outlet of the housing 1, and the sealing plate 2 slides within the movable groove of the housing 1, sealing the air outlet of the housing 1. The two sets of fixing plates 3 are symmetrically installed on the right side of the housing 1. The screw 4 is rotatably installed on the inner end of the two sets of fixing plates 3. A long groove is connected to the outer end of the movable groove of the housing 1. The movable plate 5 is installed on the lower right side of the sealing plate 2 and slides within the long groove of the housing 1. The movable plate 5 has a threaded hole and is threadedly connected to the screw 4. The motor 6 is installed at the bottom end of the lower fixing plate 3, and the output end of the motor 6 passes through the lower fixing plate 3 and connects to the bottom end of the screw 4. When heat dissipation of the outer casing 1 is not required, the two sets of motors 6 are turned on, which drive the two sets of screws 4 to rotate. The two sets of screws 4 are threadedly connected to the two sets of moving plates 5. The two sets of moving plates 5 drive the two sets of sealing plates 2 to slide at the air inlet and air outlet of the outer casing 1 until they are sealed. By setting this device, when heat dissipation of the outer casing 1 is not required, the air inlet and air outlet of the outer casing 1 can be sealed, thereby preventing dust from accumulating on the relay and its electronic components and ensuring its reliability.

[0020] As a preferred embodiment of the above, a fan 7 is also included, which is installed at the air outlet of the housing 1; By setting up fan 7, when the temperature inside the casing 1 is high, fan 7 is turned on, which speeds up the airflow inside the casing 1, thereby improving the heat dissipation effect.

[0021] As a preferred embodiment of the above, a dustproof net 8 is also included, which is installed at the air inlet of the outer casing 1; By setting up a dust filter 8, when air enters the housing 1 through the air inlet, the dust filter 8 can filter impurities in the air and improve air cleanliness.

[0024] As a preferred embodiment of the above embodiment, a sealing ring is provided on the outer side of the sealing plate 2; It can improve the sealing performance between the sealing plate 2 and the outer shell 1.

[0025] As a preferred embodiment of the above, the multiple temperature sensors 9 are electrically connected to the fan 7 and the two sets of motors 6; When multiple temperature sensors 9 detect that the temperature inside the casing 1 is high, they control two sets of motors 6 to open, opening two sets of sealing plates 2 and simultaneously turning on the fan 7. The fan 7 improves the heat dissipation effect on the casing 1. When multiple temperature sensors 9 detect that the temperature inside the casing 1 is low and heat dissipation is not required, they control two sets of motors 6 to drive two sets of sealing plates 2 to seal the air inlet and outlet of the casing 1, facilitating automatic control of the fan 7 and the two sets of motors 6.

[0026] As a preferred embodiment of the above, the outer shell 1 is made of flame-retardant engineering plastic, which meets the UL94V0 fire protection standard; It can reduce the risk of fire and improve safety.
